Connecting Nodes with the Connection Editor
Connections between nodes can be added, deleted, or changed using the Hypergraph and
the Connection Editor.
1. Start a new Maya scene.
2. Create a locator in the scene by choosing Create Locator. A simple cross appears at the
center of the grid in the viewport. This locator is a simple nonrendering null that indicates
a point in space. Locators are handy tools that can be used for a wide variety
of things in Maya.
3. Press the w hot key to switch to the Move tool; select the locator at the center of the grid,
and move it out of the way.
4. Press the g hot key to create another locator. The g hot key repeats the last action you performed,
in this case the creation of the locator.
5. Create a NURBS sphere in the viewport by choosing Create NURBS Primitives
Sphere. If you have Interactive Creation selected, you’ll be prompted to drag on the grid
in the viewport to create the sphere; otherwise, the sphere will be created at the center of
the grid based on its default settings.
NURBS
A Non-Uniform Rational B-Spline (NURBS) object is a type of surface that is defined by a network
of editable curves. Chapter 3 introduces how to create and model NURBS surfaces.
6. Move the sphere away from the center of the grid so you can clearly see both locators and
the sphere.
7. Use the Select tool (hot key = q) to drag a selection marquee around all three objects.
8. Open the Hypergraph in connections mode by choosing Window
Hypergraph:Connections. You should see eight nodes in the Hypergraph (see Figure€1.6).
